An MGLRasterStyleLayer is a style layer that renders raster tiles on the map.

Use a raster style layer to configure the color parameters of raster tiles
loaded by an MGLRasterSource object. For example, you could use a raster
style layer to render Mapbox
Satellite imagery, a raster tile
set uploaded to Mapbox Studio, or a raster map authored in TileMill, the classic
Mapbox Editor, or Mapbox Studio Classic.
